Lets a native-call user share their iPhone screen (whole device, works backgrounded). LiveKit 2.15.3 ships the broadcast stack (BroadcastManager + LKSampleHandler + IPC), so: - New Broadcast Upload Extension target "BroadcastExtension" (com.bizgaze.connect.broadcast): SampleHandler.swift subclasses LKSampleHandler; injected by mobile/scripts/add-broadcast-extension.rb which also LINKS the LiveKit SPM product into the extension + sets the App Group. Sources in mobile/ios-broadcast/. - Plugin: Room created with ScreenShareCaptureOptions(useBroadcastExtension: true); startScreenShare -> BroadcastManager.requestActivation() (system picker); stopScreenShare -> requestStop(); BroadcastManagerDelegate -> fires screenShareState to the web. LiveKit auto-publishes the track. - ios-patch.sh: RTCScreenSharingExtension + RTCAppGroupIdentifier keys. - codemagic.yaml: run the injector + sign the 3rd bundle id (.broadcast). - home.html: toggleScreen native -> start/stop; screenShareState listener reflects state + broadcasts meeting-screen so peers' stage shows it. REQUIRES a one-time manual Apple portal step: enable the App Group on the com.bizgaze.connect.broadcast App ID (see mobile/IOS_SETUP.md) or the archive fails code-signing. SPM-linked extension is new on our CI — expect build iteration. Web deployed (no-ops on builds without startScreenShare). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Inject the Broadcast Upload Extension (ReplayKit screen sharing) into the Capacitor-generated Xcode project.
|
|
# Mirrors add-share-extension.rb, with the extra step that this extension LINKS the LiveKit Swift package
|
|
# (LKSampleHandler lives in the LiveKit product), so it adds a package product dependency to the new target.
|
|
#
|
|
# WHAT IT WIRES:
|
|
# * a new app-extension target "BroadcastExtension" (bundle id <app>.broadcast) whose source is our
|
|
# SampleHandler.swift (subclass of LiveKit's LKSampleHandler) + Info.plist + entitlements, copied from
|
|
# mobile/ios-broadcast/
|
|
# * the App Group entitlement (group.com.bizgaze.connect) on the extension (LiveKit's IPC socket lives there)
|
|
# * a Swift Package product dependency on LiveKit (github.com/livekit/client-sdk-swift 2.15.3) so the
|
|
# extension can subclass LKSampleHandler
|
|
# * the extension embedded into the app ("Embed App Extensions") + set as a build dependency
|
|
#
|
|
# Idempotent: if the target already exists it is removed and rebuilt.
